Our instruments are used throughout the world in universities, research and testing laboratories, government agencies, vineyards, farms, and industrial applications.

Still Researching

Decagon was founded in 1983 by Dr. Gaylon Campbell, a renowned soil scientist at Washington State University. Dr. Campbell was (and is) an old-school physicist. When he wanted to measure something, he built an instrument to measure it. Other people wanted his creations, and eventually he couldn’t keep up with the demand. Decagon was formed to build and sell his instruments.

More than 25 years later, Decagon is a thriving company where research scientists still work to build what they and their colleagues need to do good research.

Our goal: to get the data you need into your hands in the most efficient and accurate way possible.
